Adding columns in the matrix

Hai ,

I am adding the columns in an existing matrix at runtime in page load.

I can able to add but how to give the header text for the columns added?

I tried with the following code,

oMatrix.Columns.Item("ItemMake").Title = "Make";

but it gives the error as,

"property or indexer 'SAPbouiCOM.IColumn.Title' cannot be assigned to -- it is read only"

and also i want the added column to be displayed in the first position.

Regards,

Kughan.
